Iodine is an essential trace mineral with an integral physiological role in the production of thyroid hormones (1) . Normal thyroid func-tion is essential for growth and neurodevelopment both in utero, and during childhood (2) . Thus, pregnant women and young children are considered the most vulnerable or ‘ at-risk ’ groups in terms of iodine de fi ciency (3) . There is limited information regarding iodine intakes by school-aged children in Ireland. Therefore, the aim of the current study was to estimate dietary iodine intakes from a nationally representative sample of 600 Irish children aged 5 – 12 years. The food and beverage consumption data used in this analysis was collected by means of a four-day weighed food diary during the National Children ’ s Food Survey II (NCFSII; 2017 – 2018) (www.iuna.net). The study was nationally representative of the Irish population apart from social class; thus, a statistical weighting factor was applied to account for differences. Dietary iodine intakes ( μ g/d) were calculated using updated iodine concentration data obtained from the Irish total diet study (4) and were expressed as median and interquartile ranges (IQR) using SPSS© V26.0. The percentage contributions of various food groups to overall iodine intake were investigated; in order to assess the in fl uence of milk consumption speci fi cally, participants were categorised into four groups: non-consumers, low, medium, and high consumers of milk. Median (interquartile range) iodine
